Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 12,475,775, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 12,475,775 | |
| -1 | -12,475,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,475,775.
Example:
1 x 12,475,775 = 12,475,775
and
-1 x -12,475,775 = 12,475,775
Notice both answers equal 12,475,775
With that explanation out of the way, let's continue. Next, we take the number 12,475,775 and divide it by 2:
12,475,775 ÷ 2 = 6,237,887.5
If the quotient is a whole number, then 2 and 6,237,887.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 12,475,775 | |
| -1 | -12,475,775 |
Now, we try dividing 12,475,775 by 3:
12,475,775 ÷ 3 = 4,158,591.6667
If the quotient is a whole number, then 3 and 4,158,591.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 12,475,775 | |
| -1 | -12,475,775 |
Let's try dividing by 4:
12,475,775 ÷ 4 = 3,118,943.75
If the quotient is a whole number, then 4 and 3,118,943.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 12,475,775 | |
| -1 | 12,475,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 23 | 25 | 65 | 115 | 299 | 325 | 575 | 1,495 | 1,669 | 7,475 | 8,345 | 21,697 | 38,387 | 41,725 | 108,485 | 191,935 | 499,031 | 542,425 | 959,675 | 2,495,155 | 12,475,775 |
| -1 | -5 | -13 | -23 | -25 | -65 | -115 | -299 | -325 | -575 | -1,495 | -1,669 | -7,475 | -8,345 | -21,697 | -38,387 | -41,725 | -108,485 | -191,935 | -499,031 | -542,425 | -959,675 | -2,495,155 | -12,475,775 |
